Sikorsky reveals assault helicopter proposal for US Army

The aircraft, named Defiant X, aims to be the fastest, most manoeuvrable and most survivable assault helicopter in history.

Combined with the team’s experience in mission systems, training and sustainment, the aircraft hopes to revolutionise the way the US Army meets threats in 2035 and beyond.

Defiant X will to fly low and fast through complex terrain, land quickly, deliver soldiers and equipment to the objective area (referred to as “the X”) and get out.

Defiant X flies twice as far and fast as the Black Hawk helicopter it is designed to replace. Currently undergoing testing in a digital combat environment, the aircraft continues to prove itself the most survivable platform for mission requirements.

“We are ready to deliver unparalleled capabilities backed by proven technologies that will truly transform the Army’s mission today – with room to grow and adapt to the missions of tomorrow,” said Andy Adams, Sikorsky vice president of Future Vertical Lift. “Defiant X not only includes the transformational aircraft, mission systems and revolutionary sustainment solution, but also leverages Sikorsky’s and Boeing’s advanced manufacturing capabilities.”

With its rigid coaxial rotor system and pusher propeller, Defiant X incorporates Sikorsky X2 Technology to operate at high speeds while maintaining low-speed handling qualities. This critical capability provides soldiers with increased manoeuvrability and survivability in high-threat air defence environments, allowing them to penetrate enemy defences while reducing exposure to enemy fire.

“Defiant X is purpose-built for a modernized Army that requires expanded reach, survivability and lethality,” said Steve Parker, vice president and general manager of Boeing Vertical Lift. “This weapon system will give soldiers unequalled technological advantage and connectivity over adversaries in a multi-domain battle space.”

The design hopes to revolutionise the Army’s air assault capability with limited changes in tactics, techniques, procedures, training and infrastructure while maintaining the Black Hawk helicopter footprint and tight formation capability flown today.

The Army is expected to release a request for proposal on FLRAA later this year, with a contract award expected in 2022.
